No storage device in Setup steps

I have Raspberry Pi5 with a 512GB Raspberry Pi NVMe M.2 HAT+ module.
I can successfully boot into Raspberry Pi, but when I attempt to set up Home Assistant SELECT YOUR STORAGE DEVICE is empty when “Exclude system drives” is checked. I had the same problem when I attempt this process using the SSD that came preloaded with the Pi5.

What am I doing wrong?

What is your expectation, here?
If I understand correctly, you have a single NVMe drive, so it is your system drive…

Thank you Koying for responding.

Yes, I have a single NVMe drive. I am trying to get Home Assistant up and running. However, when I run rpi-imager, in the SETUP, I select Raspberry Pi 5 → in the choose OS, I select OTHER SPECIFIC-PURPOSE OS → HOME AUTOMATION → HOME ASSISTANT → HOME ASSISTANT OS 18.1 (RPI 5), but the SELECT YOUR STORAGE DEVICE is empty and the EXCLUDE SYSTEM DRIVES is checked.

If I uncheck the system drives, I see ORIGIN:RPI-SWAP 2GB

You got me confused, as you might be.

Are you trying to image your rpi5 SSD from the rpi5?
If so, that’s not how it’s done.

You have to attach your SSD through USB to your PC, then run the imager from your PC, targeting the SSD.

I am not sure how to explain it. I cannot run Home Assistant because the Pi5 does not see the drive.

Not sure how to explicit my question, either:

Are you running rpi-imager from the RPI5? If so, that’s wrong.

A workaround would be to install an os on a SD card, then boot the RPI from the SD card and then run rpi-imager. Then you’ll be able to install haos on the SSD.

What the doc says is what I indicated above.
Do you run RPI imager from a PC with the SSD attached through USB?

No, I am booting from SSD on the NVMe

Then you have your answer. You cannot image the device (SSD) you boot from.
See above for solutions.
